A few more pics - thought I had others but this appears to be it.

Thanks - but the design was already done - but had small resonators which were way too loud. I blew sound at Thunderhill which has a limit of 103dB's and I hit 107! Had a shop in Sacramento put the Borla's in place of the resonators using the existing pipes and mounting. They did a great job. I'm at 97dB's now and with supertrapps installed can pass sound with lifting at Laguna.

I finally got a vid of my car with the new muffler setup:

sloppy day of AX in the wet, but good noises nonetheless.

Sounds good!

I guess I'm surprise. I thought that most the straight race cars ran some sort of straight pipe or a cross pipe to tip, without mufflers. You guys have some nice setups. Thanks for the photos.

All the tracks I run have sound restrictions. Laguna is the worst - but Sonoma/Sears is now more strickly enforcing their 103 dBa limit and it's the same at Thunderhill. I blew 107 with what were essentially straight pipes.
